Crowdhill Remedial Sealant
Failed sealant joints in Crowdhill need attention? We remove the old material, prepare the joints and seal them properly.
- Products that weren’t meant for the joint
- Over-sealed joints coming away
- Kitchen joints letting water behind the worktop
How we handle remedial sealant in Crowdhill
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. We work on shrunken worktop sealant, expansion joints and failed movement joints, and the jobs we see most are smears and lumps from a botched reseal and a second bead peeling off the first.
In a village or hamlet like Crowdhill, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
There’s a 12-month guarantee on every job, whatever its size.

When to call us in Crowdhill
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
Common reasons people contact us include:
- Floor or wall movement joints that have failed
- Smears and lumps from a botched reseal
- A shower that leaks however often it’s resealed
- Caulk or the wrong sealant used in a wet area
Letting a property close to Eastleigh station? Then a joint that keeps failing is best fixed properly while the property is empty.

Different surfaces, different methods
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We say so rather than reseal.
What remedial sealant looks like in Crowdhill
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
In the older streets around Church of the Holy Trinity, walls and floors in older homes can move, and sealant and grout show it first. If you look after a building such as Wyvern Technology College, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What else we do in Crowdhill
What affects the quote in Crowdhill
Jobs vary more than people expect. What affects the quote:
- Whether the work is at height
- The product the joint needs
- The old material and how stubborn it is
- The number and length of the joints
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.
What we need to know
Before you ask for a quote, have a think about:
- The problem you’ve noticed
- Pictures of the joints, sent by email
- Whether it has been sealed before
- The type of property
If you’re in Crowdhill and need remedial sealant, phone 0345 464 0079 or email us. Tell us what the problem is and where, and we’ll agree the price before any work begins.
What sealant work cannot fix
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A bath, tray or worktop that moves until it’s properly fixed
- Older mastics that may need an asbestos check before removal
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

How the visit works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. In a small place like Crowdhill, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints

Crowdhill questions
Is Crowdhill within the area you cover?
Yes, Crowdhill is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Crowdhill in your area for remedial sealant?
Yes, Crowdhill is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Can failed expansion joints be resealed?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, then the joint is sealed properly.
Leave it or put it right?
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you’ll hear it from us. Older cottages and farmhouses around Crowdhill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
